When Microsoft launched Xbox One in November, it came bundled with the Kinect voice- and motion-sensor, and sold for $500.

That may not have been the wisest move. The $500 price came in at $100 more than Sony’s PlayStation 4, which also launched in November.

Sony’s gaming console has been outselling the Xbox One for months now.

In April, Microsoft said it had sold 5 million Xbox One consoles to retailers, while Sony said it had sold 7 million PlayStation 4 units to consumers.

Earlier this month, Sony said it had sold 10 million PlayStation 4 consoles to consumers. Microsoft has not released an Xbox One sales figure since April.

Microsoft has already made a series of price cuts, including bundling top games and Xbox Live Gold membership into the price of its console.

Then in June, Microsoft unbundled the console and sensor, selling the Xbox One without Kinect for $399. Sales of Xbox One more than doubled in the U.S. after Microsoft unbundled that console and sensor, the company said in July.

The Kinect sensors allows users to control their Xbox One consoles and play games using voice and gesture commands.
